Try to find a host that will allow you to choose/select the PHP versionyou want to use, many hosts now provide this option in cPanel.

Important Note:Also make sure that your host allows crons to be run every 5 minutes,some shared hosting plans do not allow crons to be run under 15 minutes.GoDaddy and HostGator are a couple of examples that only allow cron jobsunder 15 minutes on their VPS and Dedicated server plans.
